Discussion of various types of feedback used in computer-assisted instruction focuses on a study of low-ability eleventh graders that compared the effectiveness of answer until correct (AUC) feedback with knowledge of correct response (KCR) feedback. Achievement data on posttests as well as time data are analyzed. (11 references) (LRW)

Proposes an empirico-statistical model to differentiate dependent and independent historical texts. Formulates a regard for information principle and an amplitude correlation principle. Experimentally examines and validates the model and both principles using specific historical texts. Includes tables and graphs. Appends further discussion of the…

Reviews organizational approaches adopted in different countries for resource management in distance education and compares the cost structure of distance education and conventional education. Resource implications of alternative organizational approaches are briefly examined. Ireland's cooperative approach is described and cost-effective computer…

This study analyzed CD-ROM searches in five science and engineering databases in an academic library. Results indicated that users were usually able to obtain results and print records but that few used more sophisticated techniques to refine their searches. It was concluded that instruction in CD-ROM database searching should be a high priority.…

Discusses hypermedia; examines cognitive theories of learning and hypermedia; and describes hypermedia applications in science education, including physical delivery of information, curriculum design, and promotion of scientific inquiry. Research projects at Vanderbilt University dealing with aspects of science education, including elementary…

Reports study results of introductory psychology students preparing for a quiz using programed instruction, reading a text, or reading an unrelated text. Lists principles of learning, including clear learning objectives, small steps, logical sequence, active responding, and drill and practice. Concludes that programed instruction is highly…

Effects of group and individualized mathematics instruction were investigated in high and average ability elementary students, noting the impact of ability grouping on achievement. Students instructed in pairs scored higher on posttests than those working alone. Ability grouping influenced the nature of intragroup interaction. Generating and…

Discusses large-scale electronic networks, scholarly communication, and collaborative research, and describes a study that investigated a process of identifying authors important to information transfer within a scholarly network of collaborating authors. Empirical measures of productivity, grantsmanship, impact, and influence are described, and…

This study examined the effectiveness of a computer algebra system in teaching secondary school mathematics. Pre- and posttest results and time on task were compared for students receiving conventional instruction and those receiving computer-assisted instruction using an enhanced version of muMath, a standard computer algebra package. (four…

Compares the performance of education undergraduates with high or low spatial-skill scores who learned how to calculate surface area using hypertext, computer-assisted instruction, conventional paper materials, or program control. Results are reported for misconceptions, correct problems, time on lesson, enjoyment rating, screens viewed, and…

Provides a national perspective on the prevalence and nature of interventions in grades 4 through 8 to increase participation of minority students and females in mathematics and science. In all, 163 programs responded to the request for information. The range and extent of these interventions are described. (SLD)

Discusses methods for teaching mathematics skills and describes a study of third graders that compared student performances on worksheets, a microcomputer drill and practice program, and daily one-minute timing procedures of precision teaching for independent practice of multiplication facts. Results indicate that precision teaching was the most…

Reports results of 1990 study that examined user satisfaction with OPACs (online public access catalogs) at 5 Ontario universities through interviews with 2,916 students and faculty members. Data on OPAC and computer experience, learning methods, and the effects of several variables on satisfaction are analyzed for the entire sample and for each…

Discussion of humanities research focuses on activities of the British Library Research and Development Department (BLRDD), particularly the Humanities Information Review Panel.
